It's been quite a while since we proposed a novel solution for ridding our cities of dog poop -- DNA registration of pets, and subsequent DNA identification of wayward dung -- but it seems to be slowly, slowly gaining acceptance. The Israeli city Petah Tikvah gave it a try, and now the New York Postreports (and Gothamist follows) about an apartment complex in Rockville Center, Long Island, that's using the DNA method to punish owners who don't pick up after their dogs. Good to see the power of poop still rolling on.
